摘要
为定量描述水系形态结构特征,首先运用ArcGIS软件对淮河流域水系进行了提取和修正;其次,基于分形理论,且充分考虑到人工水系的建设情况,借助MATLAB软件程序对淮河流域13个水资源3级分区考虑和去除人工水系情况下的水系盒维数进行了计算;最后,对计算结果和流域内其他特征参数进行了讨论分析.结果表明,水系盒维数可以较好地表征流域内水系形态结构,且能在一定程度上反映出流域人类活动、水系发育情况、地貌特征、土地利用情况等.
In order to quantify the characteristics of river system form structure, the river system of the Huaihe River Basin is extracted and modified firstly by using ArcGIS software. Based on the fractal theory and the construction situation of artificial river system, river system box dimension of 13 water resources third-grade districts in Huaihe River Basin is calculated under the condition of artificial river system and without condition of artificial river system by using MATLAB producing procedure. Finally, the calculation results and watershed features are discussed. The results show that the form structure of river system can be characterized well by river system box dimension, which can reflect the human activities, development of river system, geomorphic feature and land utilization to some extent.
